- Did we just blow below passive house?? I can’t believe how good of a blower door test score we ended up getting! This lays to rest once and for all just how good and efficient a post frame, pole barn, or timber frame building really can be! If you want, let me know in the comments below and Ill make another video going over this test and why I think we scored so well! Keep in mind Passive house is anything below .6 ACH50...we Killed IT!!

This is a good book. Does provide a step by step introduction to how to build things th-cam.com/users/postUgkxhgbP-6hUnXu_QRaoHgLztgsI0YF3HqR0 , also does offer some steps. Includes pictures to give you ideas for layouts and such. If you are looking for a guide, this is not exactly what you want. But if you are trying to familiarize yourself with the way that pole barn building and other out buildings, are made, then this will work just as you need it to. A few things in this book are a barn (of course), detached garage, storage building, and coops.
Yes!!!! Randy on the Channel! Way to go Kyle! Killer job. But, I have to say I’m a but jealous as I’m just realizing your channel has eclipsed mine. Dang it! Congratulations Buddy. Well deserved! You are building some awesome Projects. Keep killing it!
Thanks Matt! You were a huge inspiration for a lot specifically doing this blower door.
Dope that two of my favorite building TH-camrs are both doing so well AND humble AF.
I've been in commercial construction for 30 years and both you and Matt have taught me an incredible amount of tips and assemblies. Much appreciated gentlemen
Awesome! We might have just set the record for worlds tightest home over here in Canada. Our data results are being verified by The Energy Conservatory. Once verified, you'll be hearing from us. You need to hear my story and how your channel changed my life..... Hint, we're under 0.04ACH@50Pa
One of the most important videos on air tightness, because it didn’t use crazy exotic materials, just quality work! Well done.
WOW!!!! That score is super low and you weren't even trying to get passive house standard. This is a credit to your attention to detail. Nice job!
Big thumbs up to modern building materials as well! Funny to watch 15 year old builds where they obsess over details and don’t come near this result.
Matt is a great guy but often he seems swayed by trendy products that seem good or advanced techniques that aren't best practices.
@@tedsheldon11 when you typed 'swayed' i think you meant to say sponsored.
A blower score is a great way to not only grade the quality of work by the contractor/s, but also the quality of the products and their implementation in the construction process. Congratulations guys on a job extremely well done!
I'm seriously considering moving, just so we can have you guys build our future post frame/barndo home. Absolutely love your attention to detail and pride of work. This is an exellent example of how your care and craftmanship pays off! Congratulations! Thank you for sharing!
The craftsmanship is evident; really great job on this build. Wish I had a barndo just like this one!
That 1200 CFM exhaust fan will draw air through that wood-burning stove if they’re not careful very important! You are awesome! Loved this build video. Would love to see more from you.
This is a good video and I will be showing this to my students during our alternative building materials and heat-loss and gain calculation lessons. Thanks for making this video Kyle!
I remember Matt Risinger needing to add a filtered air intake for a range hood on one of his projects. It’s an amazing achievement when a building is sealed that well.
ERVs and HRVs are used on a ton of Matt’s builds for fresh air, was nice to see him explain the use case of why in his passive house video
Hey, congratulations. One of the reasons I watch your channel is your attention to detail. It's a big strength of yours, thank you for sharing it with the world.
I am really not shocked. I mean you build with a high level of attention to detail. And post frame makes sense due to so few spots of thermal bridging vs 16" oc stick built. Love watching you frame it's such a cool site to see!
You described my my house that was built in 1997. A mouse will fart two counties over and I'll feel it. I argued with the builder to wrap the house and seal it up better and he would not saying it needed to breath. He didn't0 even put anything under the shingles, just particle board and shingles. AND I am freezing to death as I type, sitting here in my cold weather bibs and coat.....thanks you thank you thank you Carhartts. If it wasn't for them, I'd be a human popsicle.
Great score Kyle! My students really like doing the blower door test on our homes we build each yeah. They are excited to test the duplex when we finish it up. Thanks for the great content and for the amazing tools we've been using!!
I haven’t been watching TH-cam as much lately, work is crazy and sometimes being your own boss you don’t want to come home and think about the job site. I have to say I was supper happy to read the title. I appreciate the professionalism you show in these videos. Doing things to a high standard and enjoying the work along the way. Every time I watch a video I feel a bit more encouraged and excited for the future in this industry. Y’all keep up the good work.
Very informative video Kyle. Yes you did it to see how you scored for your build but also to educate us out here. Thank you for that.
Congrats Kyle and Greg for a great job. Attention to detail pays off.
I've been waiting for this to be done and had requested it many times! Thank you 🙏🙏
That just shows that your detail work is awesome 👌 You didn't even try to make the numbers & now you know and could even improve on what you found out !
This score is truly impressive. Great job!
Amazing craftsmanship and overview of this simple, yet complex, process! Educational in many respects
This is one of the best explanations and example for the test.
Very cool video. Always nice to have objective data to verify your high quality craftsmanship!
awesome job Kyle!! Loved this build, keep up the great work!!!
Air sealing is huge! Great work Kyle and team.
Outstanding info. I really appreciate it. Awesome score!
Great info towards the end of the video about exhaust fans and a tight house
Properly excellent video, great explanations and what an awesome score!
Thanks Kyle. Very informative! 👍😁
Great Job Kyle!
Good info. I have done the test before-and your score is VERY good.
Kyle man!!! This is awesome!!!
That door trim looks awesome!
Great video, very informative. Thanks.
excellent job guys, wish my house was even half that good
Very informative video Kyle thanks
This was really interesting. Thank you.
Very enlightening - thank you.
I feel like you and Matt from build show should get together. I think he would be very impressed!
Great video!
Well done!!!! Good stuff fosho
I watch another builder, from Texas, who goes out of his way to get good blower door numbers and seems to struggle to get numbers that good. Great job, and was happy to see the ERV. Looks like they do need a make up air system that runs when they are running their stove top exhaust.
Pretty freaking cool!!!
Very impressive your work is amazing
Looking forward to your score!
Holy cubic feet per minute bat man! Good job as always guys!
Cool man. a nice day.
Awesome info/video! I'm in hvac in Houston TX area. An option for the range hood, is having a make up air intake with motorized damper to automatically open when the exhaust turns on.
Nice to see this type of test happening in other places. In Minnesota ACH tests are mandatory on all new homes and the score needs to be 3 or lower. Scores tend to go up a bit after the home settles but at .4 I'd bet you're still under 1. Crazy! This was one of the questions I've always had watching post frame builds. Great video, very informative.
Check out a company called AeroBarrier (not affiliated) for sealing up all those pinhole style leaks programmatically. A .4 house doesn't really need it but if you were going all out.. or had another build that had a score higher than you wanted.
There is virtually no settling in a post frame.
@@christopherhaak9824 By settling I mean wood drying and all the other common things that happen in the first year of new home ownership. That certainly happens.
@@racerx00 there is nothing to dry here that would increase air leakage. There is no vertical settling, the sheathing has no drying to speak of and the seams are taped. If you can point to some drying that will occur that will increase air leakage, I would love that.
Insane man, that is awesome. 99% couldn’t achieve those numbers without air aerosol spray
Its interesting if you actually dig into the reasons why passive house wants a low ACH value. Energy is a part of it, but the main concern is actually preventing air to carry moisture into the wall. That's part of the 0.6 ACH standard for new. Retrofit can accept 1.0 ACh, but there is a sign off that says we dont guarantee the wall structure may not have moisture issues.
Very good work boys - lower than that i wouldn't worry about. Energy wise itd be embodied carbon is the current debate topic some groups are figuring out - the building part is all there - just keep showcasing and informing so its become the standard and not the "high end costly" projects.
Extremely informative and interesting. Thanks to Dan and Randy for sponsoring and making the trip! And HUGE thanks to Kyle and team for taking us along for the ride! Congratulations on your awesome build!
Thanks Brian
I live in a tract house in California, I start my fireplace on a chilly night and I can feel the cold breeze blow past my head on its way to the fireplace as it sucks in air from all over the place. It drives me crazy. I think if they tested my house, it would be 100X worse. Impressive attention to detail. When your goal is quality versus hitting production targets set by corporate headquarters, it shows.
Install an outside air supply, if possible. It helps.
Awesome!
Congratulations Kyle!
That is fantastic.
Attention to detail, is more important than poorly installed triple glazed windows and other expensive products.
At some point the value of products has a diminished ROI.
Take that Risinger! 😂 But seriously, I'm sure he would have given you the nod of approval.
I'm currently building a super tight barndo. Osb ceiling that's taped and then strapped for drywall. The only attic penetrations are plumbing vents and one wire for porch lights. Rigid foam board glued to the girts on the inside sealed to the post. I hope to be under 1ach50
Impressive results!
ah damn I learned something... thanks
@rrbuildings Congratulations thats amazing 300 cfm 50!!
Keep us in the loop on energy consumption.
If you have gas appliances please get a low testing monoxide alarm.
As you can see just a bath fan can negatively pressurize your home.
Go electric if so
Great video, when you started this project and wondered where it would land on the ach
Cozy! But what about outside folks like me who like having windows open on a nice day? Ruining the 'tight space'? I suppose I simply have windows open on a nice day now that I took the time to type all this.🤔 Good work!
I love this building science stuff! Air tightness is the most important factor in achieving a high level of comfort and efficiency in a building. If I am fortunate enough to build my dream home in the future, I will definitely hire a builder that knows how to assemble a top notch envelope. Well done!
excellent :)
There’s a system that seals off a home after all the framing, windows and doors are installed and pressurizes it similarly to this test. Once the house is pressurized they spray a fine mist or fog of a chemical sealant that builds up and seals any leaks up to like 1/4 inch in size. If there’s air escaping anywhere it will be sealed as long as it’s not too big. I can’t remember what the process is called but it can’t be beat.
Is there a final walkthrough video of the completed house?
Awesome score! Just imagine if you tried purposely to get a tight structure!
i get into this kind of content.
I got a blower door test on my 1930 + additions home and got a 15.72 😆😆😆. I'm going to get another one after my kitchen/dining reno is done and see how much I improved it.
You sure you didn’t accidentally leave all the doors open? 😂🤣😂
@@macgyver03ga Might as well have, couldn't make that much difference, eh?
hey, next time try to do a leak test without the finishing boards inside, on the exposed foil and ready installations. this will allow you to repair any leaks on the wall, now it is possible that a lot of air is hindering the finish. our result in Poland is 0.19 ach50 another thing is the fireplace, it should have an external air supply prepared at the 1st stage of construction and the fireplace itself should be with a closed combustion chamber, then you will avoid problems
Do you have a final walkthrough, I’ve watched this entire series and a little sad we couldn’t see the finished house.
I am converted to the benefit of housewrap, except for under metal siding and roofing. Need for a vapor barrier - sure, but sheet metal allows no air flow except at openings and building corners.
My self built Icf home was .14 ach 50. The guy at the time said it was the lowest he has seen. I didn’t go crazy on details. Foam roofline, anderson windows/doors and dampers on all penetrations.
Will there be another video once the family is moved in? I like to see the decor once everything is in place...like who got which bedroom, how layout of the rooms are, etc. I'd also like to know what their budget was and how close to hitting it you came. Some people would call that being nosey but I call it being "inquisitive" how the other half lives. lol
Yes, I'd like to take a #2. ;)
No exhaust fan!
Great vid. How thick was the spray foam in the walls???
Hi guys! I love your works , i love to watching your works tips and everything, in Poland I’m building wood house too and using your tips all the time , is there any chance to get work in your firm when I come to America ? I really love to work with u guys , it is like a dream for me !
Code in your climate zone is 3.0. At 0.41 you are running 9X better than code. Mazeltov.
THINKING very hard about doing Rock wool / spray foam in my barn im building in the coming months.
Great test and thanks, Kyle, do you think there is any cost benefit to putting 2 layers of house wrap around the exterior of a post frame house/shop? Just wondering. Thanks.
Maybe don't do that? Sounds like a condensation sandwich to me... maybe consider adding a higher quality product to your exterior assembly in place of double house wrap?
So the ERV wont sense the range hood running and bring in enough fresh air to satisfy it?
I'd like to see a recap video which summarizes the key details which got the score so low.
This is very educational and interesting. I’m curious, will you or your mechanical contractor make any design changes to accommodate the range hood on this build or future builds?
I’m this build my client knows all about what must be done to get full use of the fan.
@@RRBuildings Recirc?
Now need to make sure there is sufficient air exchange with the outside since there are multiple risks of too tight a house.
How many bedrooms did this one end up being? Its a beautiful home!!
Air tight houses are a fireman's nightmare. They get HOT with FUEL, then you open a door and it gets AIR to give them a face full of fire.
Dan, do you want to go #2? Nah, I went first thing this morning.
NS Builders had a hood that piped in it own makeup air because of the volume, they tested it with a couple of smoke bombs
What app was he using to see the air leaks?
How do you protect the bottom of a shed?
Yes, make up air is required for that exhaust hood. The hood supplier should have sent the make up kit with it.
@RRBuildings. Kyle, I won a prize?
I wonder if Randy used house wrap under his metal shell or if he just used spray foam on the metal.
I'm confused as to whether the various air ducts (range hood, bath fans, dryer vent) are seal before the test. If they are not sealed wouldn't they allow a LOT of air in?
Bath fans, dryers and kitchen exhaust hoods need to be off during the test but are not allowed to be sealed. This equipment along with their ducts to the outside usually leak a little air during testing. They will also leak air when the wind blows, or the home's pressure becomes negative or positive. We want testing to represent how the home would act normally. There is a testing standard called the ANSI/RESNET/ICC 380 which outlines what equipment can be sealed and what is left as found. If you find yourself having difficulties falling asleep, reading this testing standard will do the trick.
The building envelope is not the same as conditioned space. When they included the garage in the blower test they were in fact testing the entire envelope.
I know y’all got rained out and had delays on material, but how many days did y’all actually have on site working?
Does the exhaust fan in the bathroom work as efficient if the building is this tight?
The smaller exhaust fans should work as designed. Most bath fans will move between 50 and 100 CFM of air, because of both the volume and the few natural air leaks, these fans should not have any issue, though they will create a slight negative pressure in the building. The big 1200 CFM fan will not produce anywhere near that output without some sort of make-up air system or opening a window during operation.
Air tightness is one measure. What about Air Quality, VOC’s, etc that is now trapped? Would a air exchange system be recommended to ensure safe air?
we have an ERV
how do you charge for stuff like this? On smaller jobs sometimes it's hard to have an exact timeline nevermind something this size! Or do you just have enough experience to know how long it would take?
🤣 just a big ole yeti cooler. let em breathe a bit! you'll be healthier for it.
This is so tight if you were to install a or run a gas furnace or gas water heater you would literally have to have supply air for the furnace to work you couldn’t rely on the natural leakage of the house
you always supply air??
